Indonesia eSIM not connecting: the checks, in order
- Line on
- Mobile data on the eSIM
- Pick the network by hand
The short answer
Check in order: the eSIM line is switched on, it is chosen for mobile data, switching mobile data between lines is off, airplane mode has been switched on and off, and data roaming is on for the line if it does not connect. Then pick a network by hand. If it still fails, write to the store's support while you are still in Indonesia.

The checks
Step one: make sure the eSIM line is on. Second, it is chosen for mobile data, and switching mobile data between lines is off, so the phone never falls back to your home line. Step three: airplane mode on for ten seconds, then off, or a restart. Fourth, if data still will not start, turn on data roaming for the eSIM line: the store names that switch as the fix for a line that does not connect.
Pick the network by hand
In the eSIM line’s settings, turn off automatic network selection and choose each network in the list in turn. Wait a minute on each one.
When the data runs out
If data worked and then stopped, check your order page: once the plan’s data or days are used, mobile data may slow or stop until the plan ends.
Write to support
If nothing works, write to the store’s support while you are still in Indonesia, with your order page link and your phone model, and screenshots of the mobile data settings. Do not delete the eSIM while you wait: a QR code can usually be installed only once. If the eSIM cannot be made to work, you get a full refund: see refunds.
Questions
Why is my eSIM not working in Indonesia?
Work through the checks on this page in order: the line is on, it is chosen for mobile data, switching mobile data between lines is off, and data roaming is on for it if it does not start. If nothing works, write to the store's support while you are still in Indonesia.
Why does mobile data keep landing on the home SIM?
Make the eSIM line carry mobile data and switch off the setting that moves it between lines, so your home line can never take over.
